The Introductction of Cephalexin :
The Application & Function of Cephalexin :
The product is a fluoroquinolone antibacterials, with broad-spectrum antibacterial effect, especially for aerobic gram-negative bacilli high antibacterial activity, on the following in vitro bacterial with good antibacterial effect:Enterobacteriaceae most bacteria, including citric acid bacterium, Enterobacter cloacae, Enterobacter aerogenes,enterobacter, Escherichia coli rare bacterium, Cray Borrelia bacteria of the genus, proteus, Salmonella, Shigella,yersinia genus Vibrio, etc.. Norfloxacin lactate
Norfloxacin has in vitro antibacterial activity of multi-drug resistant. Penicillin-resistant Neisseria gonorrhoeae, Haemophilus influenzae and Moraxella catarrhalis is also a good antibacterial effect. Norfloxacin is Fungicide, by acting on bacterial DNA helicase of the A subunit, inhibit DNA synthesis and replication leading to bacterial death.
